You should look at this package:
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Mesh_3/Chapter_main.html

If you look at the example "Implicit domain with 1D features" and figure 
50.11 you will see the example with the spheres.

For general bodies, you'll need to use other domain oracle but in
anycase, you'll need to know the 1D intersection of the boundaries of
your domains.
